Once there was a lion and a dolphin. Dolphin was swimming in a pool when lion came along. Dolphin said, "Want to swim with me?" "Yah," Said the lion. The lion kept trying to swim. But finally he got out of the pool. He said to the dolphin, "Want to play on the playground?" "Yes!" Replied dolphin. We can play on the slide. It started to rain and the dolphin couldn't move. The lion ran away. The dolphin was yelling, "Help! help!" Then a snake came over and helped so they could get out of the rain. Snake and dolphin became friends.
